NAME
pwconv - install and update /etc/shadow with information
from /etc/passwd
SYNOPSIS
pwconv
DESCRIPTION
The pwconv command creates and updates /etc/shadow with
information from /etc/passwd.
If the /etc/shadow file does not exist, this command will
create /etc/shadow with information from /etc/passwd. The
command populates /etc/shadow with the user's login name,
password, and password aging information. If password aging
information does not exist in /etc/passwd for a given user,
none will be added to /etc/shadow. However, the "last
changed" information will always be updated.
If the /etc/shadow file does exist, the following tasks will
be performed:
Entries that are in the /etc/passwd file and not in the
/etc/shadow file will be added to the /etc/shadow file.
Entries that are in the /etc/shadow file and not in the
/etc/passwd file will be removed from /etc/shadow.
Password attributes (e.g., password and aging
information) that exist in an /etc/passwd entry will be
moved to the corresponding entry in /etc/shadow.
The pwconv program is a privileged system command that
cannot be executed by ordinary users.
FILES
/etc/passwd, /etc/shadow, /etc/opasswd, /etc/oshadow
